CHARLES ELEoK, OF WEST HOBOKEN, Ann GERMAN R. MAGEE, E NoE'rH BERGEN, NEW JERSEY.

To all whom it may concern:

Be it known that we, CHARLES FLECK, a

' citizen of the United States, residing at West Hoboken, in the county of Hudson and State of New Jersey, and GERMAN R. MAGEE, a citizen of the United States, residing at North Bergen, in the county of Hudson and State of New Jersey, haveinvented a new and useful Emergency Stop-Valve, of which the following is a specification.

Our emergency stop valve relates to a collapsible and expansible valve whereby passage is permitted through the valve case when the valve is collapsed and prevented when the valve is expanded, and the objects of our invention are first, to provide an emergency stop valve whereby the passage of steam, fluid or liquid is permitted or prevented, the valve being used as an independent means for this purpose, second, to provide an emergency stop valve which may be used in conjunction with a valve located in a position interior to our emergency stop valve, whereby in the event of the breaking of such second valve a stop means is had to prevent the passage of steam, fluid or liquid to the broken or inoperativevalve, thus permitting repair of such second valve or the substitution of another valve therefor; third, to provide an emergency stop valve which when used in conjunction with an interior valve may be inserted into the nozzle or entrance connecting such second valve with the source of supply of steam, fluid or liquid; fourth, to provide an emergency stop valve which may be operated from a point adjacent to the valve or from a point remote from the valve, as 1n the case of a ship by means attached to the valve in the hold,

or by means located on a higher plane or deck in a position remote from the valve;'

and fifth, an emergency stop valve. which is simple in construction and operation and cheap to manufacture.

To the accomplishment of the above recited objects and others of a similar nature our invention consists in the construction,

combination and arrangement of parts set forth in and falling within the scope of the appended claims. And it should be understood that we donot confine ourselves to all the precise details of construction, as there Specification of Letters Patent.

EMERGENCY STOP-VALVE.

Application filed October 30, 1913. Serial No. 798,214.

tain respects without departing from the spirit of our invention or exceeding the scope of the claims.

We attain these objects by the device illustrated in the accompanying drawings in which- Figure 1, is a longitudinal section of our emergency stop valve on the line 11 of Fig. 3. Fig. 2, is a longitudinal section of our emergency stop valve on the line 22 of Fig. 3. Fig. 3, is a cross section of our emergency stop valve. Fig. 4, is a view of our emergency stop valve illustrating a method that can be used to operate the same from a point remote from the location of the valve.

Similar numerals refer to similar parts throughout the several views. a

Our emergency stop valve comprises-a case, 10, and a valve, 11, having two leaves or semi-circular portions, 12 and 13. 'The case, 10, is cylindrical in form and is provided in its interior with a seat, 14, for the valve, 11. The front end or end toward the supply source, of the case, 10, may be flanged to the outside wall or side of the case of a vessel such entrance or inwardly extending nozzle being customarily provided for the introduction of water for use in the vessel.

. Each of the leaves, 12 and 13, of the valve, 11, has a hinge portion or enlargement, 16, bored longitudinally to receive a shaft or spindle, 17, which connects the leaves, 12 and 13, and upon which the leaves turn, each leaf being joined to its hinge enlargement, 16, by a flange, 18. Each leaf, l2 and 13, has at its outer end a bevel, 19, which engages with the seat, 14, of the case 10, when the valve, 11, is in position closing passage through the case, 10, the bevels, 19, and the cave surface, 20, and the leaf, 13, is provided with a convex surface, 21, which engages the concave surface 20, when the valve, 11, is expanded or in position closing passage or flow through the case, 10, the parts being ground or otherwise .arranged to make a close engagement, the intention being to prevent leakage through these parts of the valve into the case, The hinge enlargement, 16, on the inner end of the leaf, 13, has a nose or projection, 22, which engages a recess, 23, in the hinge enlargement, 16, 011 the inner end of the the extendedend of the shaft or spindle, 17,"t'he shaft or spindle, 17 being fastened by a pin, 29, to the extended end of the hinge enlargement, -l6,of the leaf, 12, so thatthe leaf, 12, will turn with the spin dle, the bevel gears, 27 and 28, being arranged to turn in opposite directions in response to the turning of the bevel gear, 27, the eflect being to turn upward the leaf, 12, to prevent leakage at this point, leaves, 12 and 13, until they form a disk the parts being ground or otherwise"arrangedto make a close fit, the inner ends of the hinge enlargements, 16, "also being ground or otherwise arranged closely to connect to prevent leakage into "theca'se 1O, on the line of contact *of 'tl'l'e'in'ner ends of "the said hinge enlargements. The hin'ge enlargement, 16, of the leaf, 12, is ekteilded on its side throughthe ca'se, 10, "an'd also 'through the entrance orfno'Zzl'e, 15, 'as the case may *be, and the hinge enlargement, 1 6,'ofthe'leaf, 13, is extended on its side through the case, 10,and through'the entrance or nozzle, 15, asthe case maybe,'the shaft or spindle, 17, also being extended therethrough onthef'sid'e of'thefleaf, 13, a stufling box,"2el, or other means beinguse'd to prevent leakage at the points of extension into the object 'orvess'el on which our device is used.

V The operation of our emergency stop valve is'asfoll'ows: The parts'havin'g been assembled in the case, j-10,when"the valve is used independently 'the case is attached "at its lower or outer end, 'orend toward the source of supply, tothe outside wall of the object with which it ise'mpl'oy'ed, such as "the outside )lankin 'df'a vessel an'dthe upper or inner end connected to "the desired pipe, the leaves,12 and 13, being 'c'ollapsed, as shown in outlin'efFi'g. t0"'per- Imit passage throughthe valve, 11, to the desired pipe. To prevent passage through the valve a' turning movementis applied'by cranlohandle orother suitablemeans'to the extended end of each of the leaves, 12 and 13, to turn the hinge enlargementfltifof "each leaf in an opposite direction onthe spindle'or shaft, '17 the "eil'e'ct being to turn thele'aves upward so that the valve 'forms "a disk which engages the seat, 1 1, of the case, 10, and thus closes passage th'erethrough.

rangementshown in Figs. andi'l may be employed, which comprises a'sliaft, 25,'ex-

tending from the deck downward supported bya bracket attached to'the outside ofthe fc'ase, 10,andfhaving at its lower 'end abe'vel gear, 2 6,engaging with a bevelgar. 27,

attached to the extended end of the hinge enlargement, 16, of theleaf, 13, of the valve,

11, anew-1th a bevel gear,"28, attachedto engagingtheseat, 14c, of the case, 10, and closing passage therethrough. To open the valve 11, for passage thefmeans for operatioinivhether'in'closeiproximity to the valve, 1 1, or "located remote therefrom, the reverse of "the "above described turning movements is employed whereby the leaves, 12 and '13, are turned downward and the valve, 11, collapsed 'as shown in outline, Fig. 1, to permit 'passage-throughthe case, 10. But "we do'no restrict ourselves'to either ofthe above dew z'ibed means for operation, either 'iin'mediai-i to our deviceor operated from a 'distan e therefrom whereby the leaves, 12'and 18, may be expanded or collapsed to prevent or "permit passage through the case, "10, but elai'nrany means for operation *by whiehtheleaves, 12'an'd 1 3, may be 001- lapsed or expanded to permit or prevent flow through the case, 10, as within the scope of our invention.

lVhe'n our emergency stop valve is'used in "co11junction'with an'entrance or nozzle, 15,'the case, 10, is inserted into the entrance orj'nozile, 15,fsofthat the flange atthe top orinnerfend 'of the case, 10,'engages with the flange at the "top "or inner end of the entrance o'iflnoz'zla the engaging surfaces of the flanges being ground or otherwise arranged" to fit tightly to prevent leakage between the case, 10,and"the entrance 'ornozz'le,15,"a't this point,the"means of attachnient being couiiter 'sunk in "the flange of the case,' lQ," so 'as "to providefasmooth surface to whichthe interior'valve,when our device is used with an interior valve, may b'e bolted or-otherwiseattachedto make a tight fit "and prevent leakage between the flangebfthe valve, 11, and the interior valve. v
